Hey brothers can u help me i have a problem when i will install vBulletin in my host there is a problem look here:
Code:
Fatal error: Call to undefined function verify_optimizer_environment() in /home/vol4/0fees.net/fees0_2658747/htdocs/install/installcore.php on line 149
That function, "verify_optimizer_environment()" is suppose to be in /includes/adminfunctions.php and the installcore.php is suppose to have a require_once reference for it.
check first, that /includes/adminfunctions.php exists. Sometime FTP doesn't upload what you thought it did.
Double check that
"require_once(DIR . '/includes/adminfunctions.php');" is at the top of your installcore.php file.
